We just made it through the summer solstice, and these next few hot months will have many of us running toward any available water sources to keep cool. It can be disappointing to arrive at our favorite watering hole and find it packed with people, but the theme park-goers in the video above from Tokyo Summerland don’t seem to mind sharing. In fact, there seems to be more humans than water in this wave pool. Although being so close to all those other bodies looks uncomfortable to me, in Japan, people are more used to having little-to-no personal space in public places – as evidenced by all those videos of trains being packed with people with a little help from station attendants.
